What has 4 electrons 4 neutrons and 4 protons?
The isotope of Beryllium, 8Be. It is very rare and very unstable: with a half life of 7*10-17 seconds (70 quintillionth of a second!).
What does the 3 indicate in Al 3 plus?
Thagt it has lost three electrons. Aluminium metal has 13 protons(+) and 13 electrons(-), as the neutrally charged atom. However, as the aluminium cation it has 13 protons(+) and 10 electrons(-) in the charged ion. (+)13 (-) 10 = (+)3 Hence its ionic charge is Al^(3+).
What unit are nucleus measured in?
Atomic mass unit; protons and neutrons both weigh about 1 amu1 amu equals approximately [1 gram / (6.023 * 1023)] = 1.66 * 10-24 gramsThe angstrom (symbol Å) is often used to measure distances at the atomic scale.1 angstrom = 10-10 meter, or 0.1 nanometer
Do electrons have mass?
Yes, electrons have a mass of 9.1094 X 10−31 kg.
How many electrons have a charge of 10 into 10 power -6 coulomb?
To get the number of electrons use the formula n = q/e q the charge given, e = elementary charge which is of electron or proton So n = 10 x 10-6 / 1.6 x 10-19 Hence number of electrons = 6.25 x 1013
What element has 9 electrons 9 protons and 10 neutrons?
The element is Neon and the isotope is 10Ne19
What has 11 protons 12 neutrons and 10 electrons?
none because the number of protons and electrons have to be the same.
What element has 8 proton 8 neutrons and 10 electrons?
The element that has 9 protons is fluorine. Its atomic number is 9, indicating that the element has 9 protons in the nuclei of its atoms. If there are 10 electrons, then the fluorine atom has gained an electron and is now a negatively charged anion with a charge of 1-.
What is neons number of protons electrons neutrons?
Protons: 10 Electrons:10 and Neutrons: 10.
What element has 10 electrons 9 protons and 9 neutrons?
The element is Neon and the isotope is 10Ne19
How many neutrons are in the atom of oxygen -18?
8
How many protons nuetronsand electrons does the element neon have?
Neon has 10 protons, 10 electrons, and either 10 or 11 neutrons, depending on the isotope.
What element has 12 protons 14 neutrons 10 electrons?
Magnesium2+ because it donated 2 electrons
How many protons does the element neon have?
10 Protons 10 Neutrons in the most common isotope.
How many protons neutrons and electrons does si-28 have?
A silicon-28 atom has 14 protons, 14 neutrons, and 14 electrons. The number of protons determines the element (silicon in this case), the sum of protons and neutrons gives the atomic mass of the isotope (28 in this case), and the number of electrons balances the charge to make the atom electrically neutral.
How many protons neutrons and electrons would an atom of neon have?
- The atomic symbol is only an abridged form of the name of a chemical element. - The chemical symbol of neon is Ne; the atomic number is 10. - The atomic number is equal to the number of protons and electrons. - Number of neutrons = Atomic mass of an isotope - Atomic number
Which element has 10 protons?
The element neon has 10 protons as its atomic number is 10.
